REEF-LAMP FOR AUTOMOBILES.

Application filed January 2 5, 1917.

To all whom t may concern:

Be it known that I, Go'r'rrnrnn E. SCHWEIZER, a citizen of the UnitedStates, residing at the city of Bridgeport, county of Fairfield, Stateof Connecticut, have 1nvented certain new and useful Improvements inHead-Lamps for Automobiles; and do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to certain new and useful improvements in a headlamp for automobiles and has for an object to improve the constructionwhereby the direct rays may be intercepted by an adjustable screen andthereby avoid a dazzling light being shown in the eyes of thoseapproaching.

Another object is to provide laterally disposed red and green lights -onthe screen so as'to guide a person approaching in passing on the greenlight side and avoiding the danger side.

rlhe invention further resides in the features of construction, and thearrangements and combinations of parts hereinafter dcscribed andclaimed, reference being had to the accompanying drawing wherein- Figurel is a horizontal section through a head lamp illustrating the presentinvention in top plan;

Fig. 2 is a front elevation of the present invention as embodied in ahead lamp;

Fig. 3 is a vertical section thereof;

Fig. l illustrates the invention as applied to head lamps when two areemployed on the front of a vehicle, and,

Fig. 5 is a horizontal section through a. lamp illustrating a furthermodification.

Referring particularly to Figs. l, 2 and 3, the preferred form of theinvention is depicted as comprising an inner, fixed hemispherical screenl, which is provided with a sleeve part 2, and a movable, outer hemispherical screen 3 that is pivoted to the fixed screen at substantiallydiametrically opposite points, as indicated at 4f.

The inner screen or screen section l has its sleeve part 2 mounted onthe lam socket 5 for supporting the screen section a ove the lamp 6,said section further being cutaway, as at 7, in its forward edge portionthrough which the light rays may pass in diverging lateral courses.

Specification of Letters Patent.

Patented July 3i, 1911"? Serial No. 144,440.

The outer screen section 3 is provided with lateral openings 8 in theleft one of which is inserted a green glass and in the right one a redglass, said openings being registrable with the cut away portions orrecesses 7 to permit of the light rays being projected through theglasses at a higher angle, as viewed in Fig. 3.

The outer screen is adjusted on the inner screen so as to intercept thedirect rays of light that would otherwise pass upwardly with a dazzlingeffect on those approaching, and permit the rays to shine from thebottom onto the road. The movable outer screen is retained at thedesired adjustmentI by set screw 9 that impinges against the fixedscreen.

Thus, upon proper adjustment of the outer screen, the direct light rayswill be screened so as not to dazzle the eyes of those approaching. rlhelateral red and green lights further aid an approaching person bydirecting him to pass the vehicle on the left and avoid the red ordanger side.

In case there is only one head light on an automobile, the red and greenside lights would be provided as just described, so that the red lightwould always show on the right hand side of the automobile and the greenlight on the left side, this being in accordance with the usual traiicrules which requlre an approaching vehicle to pass to the right and anovertaking vehicle to pass to the left.

Where two head lamps are employed it is necessary to have only onelateral opening in the outer section of each screen, such opening beingdisposed toward the adjacent side of the vehicle so as to direct therays outwardly, as shown at 10 in Fig. 4. In this instance the leftlight or glass will be green and the right li ht red, as is obvious.

ln the modification depicted in Fig. 5, both screen sections arepivotally supported between the forks of a bracket 11, the latter havinga sleeve part l2 which slips over the lamp socket 5. The inner screen 13has its rear edge concaved to closely lit the base of the lamp whereasthe outer section la carries the set screw 15 for securing the screensrelatively Xed.

in either' form it is obvious that the lamp may be completely envelopedby the screens so as to shut cut all light whatsoever, or said screensmay be adjusted to provide a small or large volume of light asconditions require. F

The outturned lip 16 provides a light-tight joint between the sectionsas Well as determines the movement of the outer screen on the inner oneby the screW 9 engaging there- With.

rJfhe parts are simply constructed and arranged and the screen, as aWhole, not only sheds the bright rays but also affords a means of guide,to those approaching, by the embodiment of the red and green lights.

lVhat is claimed is:

1. A screen for head lamps comprising, in combination with a lampsocket, an inner hemispherical screen section having its forward edgeprovided with lateral recesses, an outer hemispherical screen sectionpivoted to the first screen section and provided with red and greenlights registra-ble with the recesses thereof, and means for mountingthe screen sections.

2. In a screen for head lamps, an inner hemispherical screen section, anouter heini, spherical screen section pivoted thereto, laterallydisposed green and red lights provided Lessines in the outer section,and means for mounting the sections.

3. In a screen for head lamps, an inner hemispherical screen section, anouter hemispherical screen section pivoted thereto, laterally disposedgreen and red lights provided in the outer section, and means formounting the sections including a sleeve support.

4L. In a screen for head lamps, an inner screen section, an outer screensection, a sleeve support having a forked bracket part, and meanspivotally connecting the screen sections to the forked bracket part.

5. A screening device for head lamps, comprising a pair of pivotedscreen sections 0f spherical curvature, a light aperture in each of thesections laterally disposed on opposite sides respectively, and meansfor mounting the screens.

In testimony whereof I afliX my signature in presence of two Witnesses.
